He visited the pole and junction boxes in the road, and cut back/re-terminated our cabling, . . .

A thorough check at each individual jointing point. That's good.

. . . and also bypassed a lightening arrestor on the pole? which are known to cause issues with FTTC.

Ah, now that is interesting. I strongly suspect it was the cause of your problem.

It looks as if your service is provisioned using the Openreach 55/10 Mbps product. Assuming that is correct, the latest statistics your have shown are good.

So far we're 1 day 8 hours connected! Result. We are indeed on the 55/10 product.

We had the whole house on the internet yesterday and I could still play COD with no lag - this is in comparison to a few days ago where it would saturate and slow to a crawl - I would constantly have a lag symbol and ridiculous ping in cod!

Thanks so much for everyones input :) Muchos love!

I'm pleased to know that it has passed the "multiple game players on-line at the same time" test.  :)

Give it another day (or so) and then you might feel it appropriate to commend the Openreach technician who performed the SFI2 task? There is an Openreach "Thank an Engineer" page for such feed-back.

So, a week on: We're still getting occasional disconnections, but mostly come back at full speed. The difference now is - I can live with occasional disconnections, as long as the speeds (and connection) are stable when connected.

Disconnection today and it reconnected at 800Kbps upload, rebooted the router and it came back to near full speed.

Saturday was an issue where my parents stated the internet was more or less unusable. (Although there was apparently an engineer up the pole again Friday/Saturday). Unfortunately I wasn't here to check, and when I came back on Sunday morning (3am) the router had been connected for 18 hours at full speed.

These are the current stats

Code: [Select]
Data rate:9.465 Mbps / 55 Mbps
Maximum data rate:10.101 Mbps / 62.522 Mbps
Noise margin:3.9 / 7.6
Line attenuation:8.6 / 18.0
Signal attenuation:8.6 / 23.1

I will get that commend form done, all of the engineers have been wonderful chaps, and I don't blame any one of them for potentially not fixing the issue, it really is finding a needle in a haystack!

Edit:

I spoke too soon...

Code: [Select]
DSL uptime:0 days,00 Hours00 Mins06 Secs
Data rate:2.095 Mbps / 55 Mbps
Maximum data rate:2.095 Mbps / 59.503 Mbps
Noise margin:7.2 / 6.8
Line attenuation:8.5 / 18.0
Signal attenuation:6.8 / 23.1

It's definitely still not happy... Is there a preferred router that can give much more detailed stats? I did try putting OpenWRT onto our old Home Hub 5A, but I fried it in the process  ::) (I think it had a bad NAND as it wouldn't successfully flash)

1 hour later it disconnects again, reconnected at full speed...

Code: [Select]
DSL uptime:0 days,00 Hours00 Mins17 Secs
Data rate:9.997 Mbps / 55 Mbps
Maximum data rate:13.824 Mbps / 62.870 Mbps
Noise margin:2.1 / 7.8
Line attenuation:8.4 / 17.8
Signal attenuation:8.4 / 22.8

It's really really REALLY not happy tonight - not 10 mins after it reconnected at full speed:

Code: [Select]
DSL uptime:0 days,00 Hours00 Mins02 Secs
Data rate:5.333 Mbps / 55 Mbps
Maximum data rate:5.333 Mbps / 60.804 Mbps
Noise margin:6.1 / 7.1
Line attenuation:8.8 / 18.2
Signal attenuation:8.8 / 23.3

And back to naff. 1 - 2 disconnections every 24 hours at a minimum. Rarely comes back at full speed (55/10) now. Download completely saturating when trying to do any kind of upload task (and severe, rage inducing lag in COD  ;D)

Code: [Select]
Data rate:928 Kbps / 51.683 Mbps
Maximum data rate:1.276 Mbps / 70.155 Mbps
Noise margin:17.2 / 10.4
Line attenuation:8.9 / 18.6
Signal attenuation:7.3 / 22.6

I'm going to take the PowerLine adapters out of the loop again (have retrieved my Wifi extender out of the loft) and keep them out. Will book another engineer visit when I return, and insist on the port change if no other faults found. This has gone on long enough!

I'd get a cheap HG612 3B from e-bay and use a 2 box solution for a while as that will allow you to get much more detailed stats and may shed some light on this

Watching a few, what's the normal price for them? There's currently one for £18 B-i-n.

If you are happy to flash the firmware on it yourself when it arrives (search the site here for excellent guidance on how to do this) probably around the £20 mark.

If you don't fancy flashing it yourself (it is really, really simple though) buy an unlocked one for perhaps something around the £30 mark.

Also take a look at the HG612 stats page on this forum for the type and amount of stats you can get from it - this may give you a much better idea of what is happening, when it is happening and that might allow the educated folk on here to be able to give you some more detailed guidance.

if you're in touch with the Mods on the BT forum, ask for a visit by a "Boost" engineer/visit. Its something they should be able to raise and asking them might be easier than going through 151


Did you post on the BT forum giving a summary of your situation and asking for assistance from the mods?

They own a case until youíre happy itís fixed - and it means you have a single point of contact within BT to coordinate fixing this.

Hi,

I did post on the BT forum, but no communication at all with any mods.

Engineer has visited again today, and swapped a pair (I was sure they had already done this though!). I mentioned about the port swap and from our conversation I think that may be the next step - although it was mentioned that this is a new cabinet/equipment so unlikely to be faulty?

Current stats:
Code: [Select]
DSL uptime:0 days,02 Hours41 Mins58 Secs
Data rate:10 Mbps / 54.999 Mbps
Maximum data rate:22.933 Mbps / 57.653 Mbps
Noise margin:14.9 / 6.5
Line attenuation:8.2 / 16.9
Signal attenuation:8.1 / 21.4

Engineer has left his phone number and asked me to contact him directly in a couple of days if it goes south again!

I canít see any posts from you on that forum since early August.

You need to add a post to your last thread (or start a new one with a brief summary of the situation) saying the issue is still occurring and ask if this can be escalated to the moderators.

One of the frequent posters there can then flag your post for their attention and they will reply in that thread.

Though sounds as if you have a BT engineer taking a personal interest which is good

We've been connected 3 days so far, no dropouts. The data rate figures and also the noise margin and attenuation figures are all staying really stable now too! I think, by jove, he's fixed it.

Code: [Select]

Data rate:10 Mbps / 54.999 Mbps
Maximum data rate:22.057 Mbps / 57.691 Mbps

So, i'm back :(

I now have a HG612 in place (with my old DGND4000 router as the new BT routers don't have WAN ports eh!).

Since putting in the HG612 the connection has been solid (except for my mother turning the wrong plug off...) until today... DSLStats has only been running since this morning, forgot to leave my computer running with HG612 stats on.

What other data is useful for you guys that I can post up?

Point to note - it has rained this afternoon/evening, and has been dry for the past few days...

Cheers,

Darn that's not good, especially the upstream SNRm as I've always found things get insanely unreliable once it drops below 6dB and your speed had already gone off a cliff, no wonder it became unusable.

At least now you have clear evidence showing exactly how quickly things deteriorated and at what time, which could be useful if it coincides with the rain.  Although if they've already checked all the joins, I'm rather puzzled where the problem may be.

I find as soon as the upstream drops below about 1.5-2mbps the whole connection becomes unusable (any upload task saturates the whole connection).

The only thing that hasn't been physically inspected/touched is the cable from pole to house. The engineer did say they were replaced recently (early 2000's), the same time they replaced the big chunky bracket on the side of the house with the smaller hoop.

I was extremely tempted earlier to try and gently nudge the cable, and watch the graphs to see if it affected it at all... not sure if that's a good idea or not!. It was *very* windy early yesterday afternoon (thanks to which the drive is now covered in oil, it blew away my absorbent sheets...) and possibly was last night although I didn't go outside to check

Edit: back to decent snrm if i'm reading this right? It's been dry all of yesterday. Will monitor and get back to you guys!
